The jury in the trial of Aaron Hernandez asked the judge a key question that may suggest they are leaning toward convicting the former Patriots tight end of at least one of the crimes he is charged with stemming from a 2012 double-slaying in the South End.

“If an immunized witness provides specific testimony that we believe would give enough evidence for a conviction, do we have to have corroboration evidence for that specific piece of testimony?” the jury asked yesterday in a written note delivered to Judge Jeffrey A. Locke just before the judge returned from lunch.

In the note, the jury foreperson underlined the word “specific.”

Locke told the jury, “the direct answer is no, what you need is corroboration to at least one element of the charged crime, or crimes.”

The judge also told the jurors not to watch the show “You the Jury,” which premiered last night on the FOX network. Although the judge did not mention him by name, lead defense attorney Jose Baez is one of the stars of the show.

Exactly which witness and what piece of testimony the jury is referring to is unclear, but star prosecution witness Alexander Bradley, painted by the defense as the chief alternate suspect, was one of several given immunity to testify and likely the only one to be able to provide evidence to support a conviction.

The jury also did not specify which charge they were referring to in their question. Hernandez is charged with the 2012 drive-by shooting of Daniel de Abreu and Safiro Furtado in Boston’s South End. He also faces three counts of armed assault with intent to murder, assault and battery with a dangerous weapon, unlawful carrying of a firearm and witness intimidation.

Bradley is the only witness who has identified Hernandez as the trigger man, but the defense has claimed Bradley killed de Abreu and Furtado over a drug deal gone wrong.

Assistant District Attorney Teresa Anderson had suggested the judge offer a simple “no” in response to the question while Hernandez lawyer Ronald Sullivan asked for a longer explanation. Locke sought a compromise by answering “no,” and then offering some detail on the law.

The jurors started deliberating at 9:22 a.m. and finished at 4:09 p.m. The seven women and five men heard from a total of 70 witnesses over the course of 24 days of testimony and viewed 370 exhibits. They will resume their deliberations Monday morning.

Hernandez is already serving a life sentence for the 2013 murder of Odin L. Lloyd, and is set to appeal that conviction.
